I used Aspiring to resling 3 of my cams (2 of which were actually unusuable due to the damage to the slings) and found that they were extremely quick, very cost effective, and the quality of the work is quite high.

As you can see in Stu's original photo, the sling setup they use is closer to the classic slings of the original aliens, mastercams, etc. But as long as the revised aesthetic doesn't bother you, there are no complaints from me about the overall result.
